OK, the first thing to do is relax, remember when you are doing k2tog yo, you are creating a hole... actually you are working a lacey pattern and you need to have your work as if you were working stocking stich... if necessary, sit there with a cup of tea or a G&T and enjoy.

When you k2tog and yo, you are replacing the stitch that you have knitted together. This means that you going to treat the yo loop as a stitch and purl it as normal (I am assuming that this is a stocking stitch pattern) and continue as normal.

Remember that K2tog yo will send the holes in one direction (usually to the right) and yo sl1 psso will send them in the other direction (ie to the left).

You will get the hang of this, and you will have to rip it back when you miscount, we all do it. My sister and I made socks for each other this year and both of us admitted that as we had chosen lacey patterns at some point we had to go back a few rows... and she has been knitting for 60+ years and me for a mere 49 years. So don't despair, just give it a go, nobody dies because you are mucking about with sticks and string but lots of peeps are very happy when they see your results

Arrr, I think I'm doing it wrong! Some of the 'knit2tog' are really tight together so look like a thick stitch, others looser. Should I be knitting them as one and then the 'over' one separately? I should shouldn't I, I think I have knitted some of the together stitches separately, which will make to many stitches...?

When you k2together you are reducing the stitch count from one stitch to two. To make it back up to two, you do a yarn over. So, when,on the next round, you knit the yo and then the one stitch made by k2 tog, you end up with 2 stitches again. Not sure if that makes any sense.

Knitting in the round, a hat. Done the k2tog and yo (probably wrongly!). Do I knit all the stitches on the next row- as in both loops that are squeezed together, or treat it as one? Does that make sense?
